Personally I don't think anyone who goes into BB can be fully genuine.
They'll always need to hide something, hold back on, or act differently to situations the way they would outside the house.

Yinrun would appear the least affected of being in the house but is that a bit of an act too

It's a minefield in there of situations and emotions and reactions.
I doubt we really rarely ever see the genuine side of them.

We don't know any of them personally so I couldn't say with any certainty any of them are being their genuine selves.
